Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66996, here are decompositions:

19 + 66977 = 66996
23 + 66973 = 66996
37 + 66959 = 66996
47 + 66949 = 66996
53 + 66943 = 66996
73 + 66923 = 66996
107 + 66889 = 66996
113 + 66883 = 66996

Showing the first eight; more decompositions exist.
